British model Cara Delevingne shocked the world when she swapped her long locks for a bald head

French designer Coco Chanel said: “A woman who cuts her hair is about to change her life.”

So when should you get a new do? Model Cara Delevingne recently shaved her head while Bella Hadid dyed her brown locks jet-black, saying: “When you dye and cut your hair, it takes away a lot of past resolutions.”

Here, JENNY FRANCIS dares four women stuck in a hair rut to transform their look with the help of hairdresser and Salon Science ambassador Andrew Jose, plus hair extension specialist Vixen & Blush.

Black to dark blonde

DARK-HAIRED Lucy Smith, 33, is dying her hair lighter for the very first time. The accountant and mum of three sons and two stepdaughters never thought of going blonde because of her complexion. She says:

"I have dark brown hair naturally but have been dying it black from my twenties. I don’t think about it really, I just do it out of habit.

The new blonde bombshell said her new hairstyle suits her personality and her family loves it

Blonde to brunette

MEDICAL secretary Diane McGowan, 43, hopes her change of colour will give her a new lease of life. The mother of one, from Abbey Wood, south-east London, has had a year of big decisions and thinks going darker is a great way to move forward. She says:

"I’ve gone from being very overweight and unhealthy to slim and happy after having gastric bypass surgery. I lost 14st.

Medical secretary Diane said she finally has the confidence to rock a bolder look

After her transformation, Diane says: “I’m surprised at how much I like it. I thought it would be harsh on my skin tone but it looks clean and fresh.

“Being blonde my whole life, people sometimes think I’m a ‘dumb blonde’ or men have assumed I’m ‘easy’. It will be really interesting to see if I get taken more seriously now. I’ll have to invest in a darker eyebrow colour to match it.

“My dad was really surprised. He didn’t recognise me! Only one person to has said they don’t like it so far. That doesn’t matter, though – I love it.”

The mum-of-one said her father barely recognised her with her new hairstyle, but she loves it

Straight and short to long and wavy

TEACHER Natalie Evans has always had short hair – but says she has been trying to grow it for years. The 38-year-old, who comes from Weybridge in Surrey, admits that her thin locks have been ruined by continuous straightening, causing her hair to split.

She says: "My hair has never grown past the top of my shoulders and I find it really frustrating.

Natalie Evans said she has had countless compliments since her hair makeover

After Natalie’s transformation, she says: “I can’t believe how much it suits me. I put a picture on Facebook and everyone was so surprised when they saw it and complimented me on how it looks.

“Most people think I’ve just grown it – that’s how natural it looks.

“I look younger and more glamorous. I can’t imagine going back.”

Long to short crop

SINGLE mother of one Catherine Ely admits neglecting her hair for decades and hasn’t a professional cut in four years. The 42-year-old, from High Barnet, North London, is director of non-profit organisation Resources For Autism and has cared for her ill 15-year-old daughter for the past four years. She says:

"Juggling caring for my daughter with a demanding job means my hair has been somewhat neglected and is now very thick and long.
